ObjectiveThis paper aims to investigate and evaluate the staged efficacy and safety of the representative empirical prescription of the “Zhu Ke Jiao” theory， Qijia Rougan prescription， combined with entecavir in the treatment of hepatic fibrosis in chronic hepatitis B. MethodsA multicenter randomized controlled clinical study was conducted， and 101 patients diagnosed with chronic hepatitis B-related hepatic fibrosis （CHB-HF） who met the diagnosis and inclusion criteria were randomly assigned to an observation group （Qijia Rougan prescription + entecavir） and a control group （entecavir）. The treatment duration was 24 weeks. Liver stiffness measurement （LSM）， fibrosis-4 index （FIB-4）， portal vein diameter， hepatitis B serology， biochemical indicators， hepatic fibrosis markers in serum ［hyaluronic acid （HA）， laminin （LN）， procollagen Ⅲ peptide （PⅢP）， and type Ⅳ collagen （Ⅳ-C）］， and traditional Chinese medicine syndrome scores were used as efficacy evaluation indicators. Efficacy assessments and explorations of different staged subgroups of Qijia Rougan prescription were conducted according to LSM values based on the Metavir pathological staging standard. ResultsA total of 98 cases were included for statistical analysis， with 49 cases in the observation group and 49 in the control group. The general data of the patients in both groups were comparable. Compared with the same group before treatment， the observation group showed a significant reduction in LSM and FIB-4 （P<0.01）， as well as notable improvements in LN， Ⅳ-C， and various TCM syndrome scores （P<0.05， P<0.01）. When compared to the control group after treatment， the observation group demonstrated significant improvements in LSM， FIB-4， and various TCM syndrome score indicators （P<0.05， P<0.01）， indicating that the observation group performed better than the control group. Subgroup analysis of the regression of hepatic fibrosis stages showed that compared to the same group before treatment， the observation group had better improvement in regression of stages F2 and F3 （P<0.05）. When compared to the control group after treatment， the observation group exhibited superior improvement in regression of stage F3 （P<0.05）. No adverse events occurred in either group during the treatment period. ConclusionCompared with entecavir alone， the combination of Qijia Rougan prescription and entecavir significantly improves the degree of hepatic fibrosis and clinical TCM symptoms in patients. The optimal intervention period is primarily during stage F3， which is a potential “interception” point of the “Zhu Ke Jiao” theory.

Objective:To investigate whether astaxanthin (AST) down-regulates dynamin-related protein 1 (Drp1) through activating the silent mating type information regulation 2 homolog-1 (SIRT1) signaling pathway, thereby attenuating contrast-induced acute kidney injury.Methods:Forty adult male Sprague-Dawley rats weighing 160-180 g were randomly divided into five groups: sham surgery group (Sham group), contrast medium injury group (CM group), astaxanthin-intervention group (AST+CM group), SIRT1 inhibitor Ex527 intervention group (Ex527+CM group), and astaxanthin combined with Ex527 intervention group (AST+Ex527+CM group). After 72 hours of modeling, heart blood was removed and kidney tissues were collected for follow-up testing. Serum creatinine (Scr), blood urea nitrogen (BUN), and oxidative stress-related indexes total superoxide dismutase (T-SOD) and malondialdehyde (MDA) were measured by biochemistry; hematoxylin and eosin staining was performed to observe the pathological changes in the kidney; mitochondrial morphology and number were observed by transmission electron microscopy; reactive oxygen species (ROS) levels were detected by ROS staining in frozen sections; TUNEL staining was performed to detect apoptosis level. The expression levels of SIRT1, p53, peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), Drp1 and apoptosis-related proteins Bcl-2 and Bax were detected by Western blotting.Results:(1) Compared with the CM group, Scr and BUN level were significantly lower, T-SOD level was higher and MDA level was lower in the AST+CM group, while T-SOD level decreased and MDA level increased after the combination of Ex527 (all P<0.05). (2) ROS expression was lower in the AST+CM group compared to the CM group and higher after the combination of Ex527 (both P<0.05). (3) The number of apoptotic cells was significantly reduced in the AST+CM group compared to the CM group and increased after the combination of Ex527 (both P<0.05). (4) The protein expression levels of SIRT1, PGC-1α and Bcl-2 were increased and the protein expression levels of p53, Drp1 and Bax were decreased (all P<0.05) in the AST+CM group compared with the CM group, and the protein expression levels of SIRT1, PGC-1α and Bcl-2 were decreased and the protein expression levels of p53, Drp1 and Bax were increased when Ex527 was combined (all P<0.05). Conclusion:Astaxanthin can inhibit Drp1-mediated mitochondrial fission by activating the SIRT1 pathway, thereby reducing contrast-induced acute kidney injury in rats.
